He's better AT it than anyone else at present. His administration is the World's number 1 agent OF terrorism.

I am sure, though, that he does not see it that way at all.

Pre-emptive war is terrorism. Threatening people with imminent attack unless they surrender to you is terrorism. Occupying a country by force is terrorism. Bombing cities is terrorism. Torturing prisoners and holding them indefinitely without fair trial is terrorism. Imprisoning and executing your own citizenry at probably the highest per capita rate in the world is terrorism. Promoting the maintenance of gross economic inequality in the World in order to acquire dirt-cheap foreign labour is terrorism.

But none of these things are called terrorism by the wealthy and powerful people who do them. No one thinks of himself as a terrorist...but if his purpose is to terrorize other people (in order to "win" or to profit) then that's what he is...a terrorist.
